The clinicopathological features of sinonasal angiomatous polyps
نویسندگان
چکیده
BACKGROUND Sinonasal angiomatous polyp (SAP) is a rare subtype of sinonasal polyp that might be misdiagnosed as a malignant lesion due to its clinical symptoms. METHODS We retrospectively enrolled the patients who were diagnosed with SAP in our hospital during 2008-2015. We analyzed the clinical symptoms, radiological findings, and pathological features of all patients diagnosed with SAP. RESULTS Unilateral nasal obstruction, rhinorrhea, and epistaxis were the common symptoms. SAPs all originated from maxillary sinus and extended to nasal cavity with or without involving the nasopharynx. Expansile mass with surrounding bony destruction is typical on computed tomography imaging but specific for SAPs. The magnetic resonance revealed high signal intensity on T1-weighted images and hypointense rim on T2-weighted images. CONCLUSION Computed tomography and magnetic resonance together might give rise to more accurate diagnosis of SAP. Incisional biopsy does help if the clinician suspects a malignant lesion. To treat SAP, complete removal is the optimal choice.
